My teenager with a lot of hair, we both tried to explain at length how we wished for it to be but she didn’t listen and ignored the request of not thinning the hair and leaving a long fringe only cut a style that she seemed to know. Several times I had to correct and by the end of it she said she doesn’t know how to cut thick hair like that. Bit late for that! I understand if there’s limitation but be honest from the start and LISTEN to what your client is asking. Then I can take the decision.
